Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wall pipe installation, in particular to a positioning and fixing device for installing pipes in a glass fiber reinforced gypsum board cavity. BACKGROUND

[0002] With the rapid development of prefabricated building industry, glass fiber reinforced gypsum board (GFRG board) is widely used in the construction of composite load-bearing walls and secondary structure partition walls due to its high industrialization degree, fast construction speed, energy saving and environmental protection, etc. The GFRG board is made of high-strength gypsum powder, glass fiber and functional additives through a molding process, and is usually designed as a large plate structure with a cavity. It can be cut into components of different specifications according to construction requirements. In the practical application of GFRG board walls, pipe systems such as water supply pipes need to be installed in the walls to meet the water supply requirements of the building. At present, the industry generally uses the "on-site slotting and embedding" post-operation mode to complete pipe installation. This technology has the following main defects: Damage to the structural integrity of the wall: slotting on the glass fiber reinforced gypsum board wall will inevitably damage its fiber reinforced structure and surface integrity, weaken the mechanical properties of the wall, and may become a potential stress concentration point and cracking source. Precision and quality are difficult to control: the size, depth and position precision of on-site slotting are difficult to guarantee, and deviations are easy to occur, affecting the quality of pipe installation and subsequent repair effect. Complicated process and low efficiency: multiple wet operation processes such as slotting, installation and repair need to be carried out in steps, with long construction period, low efficiency and high labor cost. Environmental pollution: the slotting process produces a large amount of dust and noise, polluting the construction site environment and endangering the health of workers, which does not meet the requirements of green construction. Repair quality risks: the quality of slotting repair depends on the skills of workers, and defects such as imperfect repair, hollowing and cracking are easy to occur, affecting the final finishing effect and long-term durability of the wall. Low industrialization degree: this process highly depends on on-site manual operation and cannot achieve standardized and modular industrialized production and installation.

[0003] In summary, the existing GFRG board wall pipe installation process has many defects, which has become a key bottleneck restricting the development of prefabricated building industrialization. Therefore, it is of great practical significance and industrial value to develop a pipe positioning and fixing device and installation method that can avoid on-site slotting, achieve factory prefabrication, ensure installation precision and meet the requirements of green construction.

DETAILED DESCRIPTION

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1: like Figures 1-8 As shown, this embodiment of the invention provides a positioning and fixing device for installing pipes within the cavity of glass fiber reinforced gypsum board, comprising three core components: a square front base box, a square rear base box, and a sealing plate. These three components work together to achieve the positioning, fixing, and sealing functions of the pipe. The specific structure is as follows: Core positioning and fixing components: square front bottom box and square rear bottom box; Both the front and rear bottom boxes are made of flame-retardant engineering plastics, preferably ABS or PC. These materials have good mechanical strength, impact resistance, and flame-retardant properties, and can withstand the pressure during self-compacting concrete pouring and subsequent temperature and humidity changes in the environment. They are also lightweight, facilitating factory prefabrication and on-site handling. The snap-fit ​​connection structure allows for tool-free, rapid assembly. The outer walls of both the front and rear bottom boxes have matching snap-fit ​​structures. Each of the four corners of the front bottom box has one slotted hollow cylindrical snap-fit, and each of the four corners of the rear bottom box has one... The solid cylindrical buckle with protrusions is used to align the hollow cylindrical buckle of the front bottom box with the solid cylindrical buckle of the rear bottom box during assembly. Axial pressure is applied to push the two bottom boxes closer together, and the solid cylinder is gradually inserted into the hollow cylinder. The protrusion at its end will squeeze the slotted side wall of the hollow cylinder, causing the side wall to elastically deform outward. When the protrusion slides completely into the slotted position, the side wall of the hollow cylinder rebounds and resets under the elastic action of the material, and the protrusion is locked into the slot, forming a strong mechanical interlock. This connection method does not require any tools, the assembly time is only 10 seconds, and it can automatically achieve coaxial alignment of the two bottom boxes. Pipe positioning slots: Semi-circular pipe slots are provided on the inner walls of the front and rear base boxes respectively. The diameter of the slots is the same as the outer diameter of the pipe to be installed, and the depth of the slots is 1 / 2 of the outer diameter of the pipe. After the two base boxes are assembled, the two semi-circular slots form a complete circular through hole. The pipe is tightly wrapped in the through hole and cannot be radially displaced. At the same time, the position of the slots is controlled by a high-precision mold to ensure that the distance between the center of the outlet of the pre-installed pipe fitting and the front of the base box is fixed, and the coordinate error of the outlet center relative to the outer wall of the base box is ≤0.3mm. This lays the foundation for the subsequent alignment with the installation holes of the glass fiber reinforced gypsum board wall panel. Temporary fixing and sealing components: sealing plate: The core role of the blocking plate is to temporarily fix the pipe-bottom box integrated module on the glass fiber reinforced gypsum board wall plate during the factory prefabrication stage, and seal the gap between the module and the wall plate mounting hole, so as to prevent the leakage phenomenon during the subsequent site pouring of self-compacting concrete. The blocking plate is made of the same flame-retardant engineering plastic as the bottom box, and has a square shape. The length and width of the blocking plate are larger than the mounting hole of the glass fiber reinforced gypsum board wall plate, so that the blocking plate can completely cover the mounting hole and avoid falling into the cavity during the fixing process. A circle of blocking plate adhesive tape is pre-stuck on the back of the blocking plate. The adhesive tape is made of foamed polyethylene, and is arranged along the edge of the blocking plate to form a closed rectangular ring. The inner side dimension of the ring is consistent with the size of the mounting hole of the glass fiber reinforced gypsum board wall plate. When the blocking plate is attached to the surface of the glass fiber reinforced gypsum board wall plate, the adhesive tape is elastically deformed under the pressure of the screw, so as to fill the small gap between the blocking plate and the surface of the wall plate and achieve reliable sealing. Four mounting holes are arranged on the blocking plate, which are adapted to the threaded holes of the front bottom box. The mounting holes are through holes corresponding to the four threaded holes of the front bottom box. During installation, self-tapping screws are used to pass through the mounting holes and are screwed into the threaded holes of the front bottom box, so that the blocking plate and the bottom box are firmly connected, and the sealing adhesive tape is tightly attached to the surface of the wall plate.

[0017] Example 2 The installation method of the present application is to transfer more than 80% of the traditional site operation process to the factory, and the specific steps are divided into a factory prefabrication stage and a site installation stage. The factory prefabrication stage includes: Step 1: pipe pre-connection, based on the digital design BIM model, the water supply pipe and the pipe fitting are connected to form a pipe section assembly in the factory by using hot melting; Step 2: modular assembly, the pipe section assembly in step 1 is placed into the semicircular clamping groove of the square front bottom box or the square rear bottom box, and the other bottom box is aligned and spliced through the buckle structure to form an integrated module of pipe-pipe fitting-bottom box. The buckle structure includes a slotted hollow cylindrical buckle provided on the outer wall of the front bottom box and a protruding solid cylindrical buckle provided on the outer wall of the rear bottom box. During splicing, the solid cylinder is inserted into the hollow cylinder, and the protrusion is clamped into the slot to form a mechanical interlock. Step 3: accurate wall plate hole making, based on the digital design BIM model, a numerical control device is used to open a mounting hole at a specified position of the glass fiber reinforced gypsum board. The mounting hole has a diameter slightly larger than the outer dimension of the integrated module. Step 4: module implantation, the integrated module in step 2 is placed into the cavity of the glass fiber reinforced gypsum board as a whole, and the module is aligned with the mounting hole in step 3. Step 5: temporary fixing and sealing: cover the blocking plate on the mounting hole, align the mounting hole on the blocking plate with the threaded hole on the front bottom box, screw in the self-tapping screw to connect the blocking plate and the front bottom box, the blocking plate is pre-pasted with a blocking plate adhesive tape on the back, the adhesive tape deforms elastically during screwing, filling the gap between the blocking plate and the wall plate; On-site installation stage: Step 6: on-site installation and final fixing: after the glass fiber reinforced gypsum board wall is assembled on site, self-compacting concrete is filled into the cavity; after the concrete is solidified, the integrated module and the wall form a whole, the blocking plate is removed, and the bottom box interface flush with the wall surface is reserved for subsequent installation of terminal water equipment.
